Got it resolved, thanks!!
You are using your tapatalk password and not your OG forum password, correct ?
The only time I had that issue was when I somehow got logged off of tapatalk and kept using the wrong password. Since then I never log off of tapatalk, just the forum. My only guess.....
I can login through safari or internet explorer, password is correct for OG.
When I try to through tapatalk, says incorrect password.
I can login to tapatalk, login and view every forum except OG.
